Owners of property along the Palai Stream in South Hilo are receiving letters from the County of Hawai‘i, Department of Public Works this week. The letter informs them of proposed floodplain changes to the "Flood Insurance Rate Maps" or FIRMs covering their property, the processes before FIRMs are effective, and the course of action if a property is mapped incorrectly.

County of Hawaii credits the Federal Emergency Management Agency (FEMA), National Flood Insurance Program (NFIP), National Oceanic and Atmospheric Administration (NOAA) and American Red Cross for material used on this site.
